#
export DOXYGEN_PROG="@DOXYGEN@"        # Doxygen
export GZIP_PROG="@GZIP@"              # gzip (Unix-like 'gzip compressor')
export GNUPLOT_PROG="@GNUPLOT@"        # gnuplot (data plotting program)
export HHC_PROG="@HTML_HELP_COMPILER@" # HTML Help Compiler
export MV_PROG="@MV@"                  # mv (Unix-like 'move/rename files')
export PERL_PROG="@PERL@"              # Perl
export RM_PROG="@RM@"                  # rm (Unix-like 'remove files')
export TAR_PROG="@TAR@"                # tar (Unix-like 'archiver')
export WGET_PROG="@WGET@"              # wget (remote file retrieval)

# PROJECT_NAME:
# Documentation/project name. Used in some of the resulting file names and
# xrefs to uniquify two or more projects linked together through their 
# Doxygen's tag files. Mandatory for each documentation set.
# Note: might be the same as the doxyfile's PROJECT_NAME
# Example: 
#   PROJECT_NAME=VTK
#
export PROJECT_NAME=@DOXYGEN_PROJECT_NAME@

# PATH_TO_VTK_DOX_SCRIPTS:
# Path to the directory holding the Perl scripts used to produce the VTK doc
# in Doxygen format. You need the VTK source files or a local copy of 
# these scripts.
# Example: 
#   PATH_TO_VTK_DOX_SCRIPTS=@CMAKE_CURRENT_SOURCE_DIR@
#
#export PATH_TO_VTK_DOX_SCRIPTS="@DOXYGEN_SOURCE_DIR@"

# SOURCE_DIR:
# Source directory. The top directory of the source files.
# Example: 
#   SOURCE_DIR=@DOXYGEN_PROJECT_SOURCE_DIR@
#
export SOURCE_DIR="@DOXYGEN_PROJECT_SOURCE_DIR@"

# REL_PATH_TO_TOP:
# Relative path from the top directory of the source files to the directory
# (or top directory) holding the files to document. Useful if several parts
# of the same source directory should be documented separately.
# Example: 
#   REL_PATH_TO_TOP=.
#   REL_PATH_TO_TOP=framework/src
#
export REL_PATH_TO_TOP=.

# INTERMEDIATE_DOX_DIR:
# Directory where the intermediate Doxygen files should be stored (mainly
# these headers files converted from the VTK format to the Doxygen format).
# This directory is erased at the end of this script, unless you comment
# the corresponding line.
# DOXTEMP might be used to simplify the syntax.
# Example: 
#   DOXTEMP=DOXTEMP=@CMAKE_CURRENT_BINARY_DIR@
#   INTERMEDIATE_DOX_DIR=$DOXTEMP/dox
#
export DOXTEMP="@CMAKE_CURRENT_BINARY_DIR@"
export INTERMEDIATE_DOX_DIR="$DOXTEMP/dox"

# CVSWEB_CHECKOUT, CVSWEB_CHECKOUT_SUFFIX:
# URL to the CVSWeb of the project, in checkout mode (i.e. appending a file 
# name to this URL will retrieve the contents of the file). In the same way
# CVSWEB_CHECKOUT_SUFFIX is appended to the result.
# Example: 
#   CVSWEB_CHECKOUT=http://public.kitware.com/cgi-bin/cvsweb.cgi/~checkout~/VTK
#   CVSWEB_CHECKOUT_SUFFIX=?cvsroot=CMake
#
#export CVSWEB_CHECKOUT="@DOXYGEN_CVSWEB_CHECKOUT@"
#export CVSWEB_CHECKOUT_SUFFIX="@DOXYGEN_CVSWEB_CHECKOUT_SUFFIX@"

# DOXYFILE:
# Path to the Doxygen configuration file (i.e. doxyfile).
# Example: 
#   DOXYFILE=$DOXTEMP/doxyfile
#
export DOXYFILE="$DOXTEMP/doxyfile"

# OUTPUT_DIRECTORY ALLOW_ERASE_OUTPUT_DIRECTORY:
# Path to the Doxygen output directory (where the resulting doc is stored).
# Note: should be the same as your doxyfile's OUTPUT_DIRECTORY
# If ON, allows the output directory to be erased when some advanced output
# file have been produced (HTML Help, or TAR archive for example).
# Example: 
#   OUTPUT_DIRECTORY=$DOXTEMP/doc
#   ALLOW_ERASE_OUTPUT_DIRECTORY=ON
#
export OUTPUT_DIRECTORY="$DOXTEMP/doc"
export ALLOW_ERASE_OUTPUT_DIRECTORY=ON

# COMPILE_HTML_HELP RESULTING_HTML_HELP_FILE:
# Compile the CHM (Compressed HTML) HTML Help file, name of the resulting 
# file. If set to ON and name is non-empty these options will actually 
# trigger the HTML-Help compiler to create the CHM. The resulting
# file (usually index.chm) will be renamed to this name.
# Note: if ON, the whole $OUTPUT_DIRECTORY will be erased at the end of
#       this script, since this file is considered to be one of the 
#       advanced final output, unless ALLOW_ERASE_OUTPUT_DIRECTORY is OFF
# Note: your doxyfile should be configured to enable HTML Help creation 
#       (using GENERATE_HTML = YES, GENERATE_HTMLHELP = YES)
# Example: 
#   COMPILE_HTML_HELP=ON
#   COMPILE_HTML_HELP=@DOCUMENTATION_HTML_HELP@
#   RESULTING_HTML_HELP_FILE=$DOXTEMP/vtk4.chm
#
#export COMPILE_HTML_HELP=@DOCUMENTATION_HTML_HELP@
#export RESULTING_HTML_HELP_FILE="$DOXTEMP/$PROJECT_NAME.chm"

# CREATE_HTML_TARZ_ARCHIVE RESULTING_HTML_TARZ_ARCHIVE_FILE:
# Create a compressed (gzip) tar archive of the html directory (located
# under the OUTPUT_DIRECTORY), and name of the resulting archive file. 
# Note: your doxyfile should be configured to enable HTML creation 
#       (using GENERATE_HTML = YES)
# Example: 
#   CREATE_HTML_TARZ_ARCHIVE=ON
#   CREATE_HTML_TARZ_ARCHIVE=@DOCUMENTATION_HTML_TARZ@
#   RESULTING_HTML_TARZ_ARCHIVE_FILE=$DOXTEMP/vtk4-html.tar.gz
#
#export CREATE_HTML_TARZ_ARCHIVE=@DOCUMENTATION_HTML_TARZ@
#export RESULTING_HTML_TARZ_ARCHIVE_FILE="$DOXTEMP/$PROJECT_NAME-html.tar.gz"

# DOWNLOAD_VTK_TAGFILE VTK_TAGFILE VTK_TAGFILE_REMOTE_DIR VTK_TAGFILE_DEST_DIR:
# Download the VTK tag file, name, remote location and destination dir of this
# tag file. If set to ON, the tag file is retrieved from its remote location
# using wget and stored in the destination dir. 
# The tag file is expected to be compressed using gzip, but DO NOT include
# the .gz extension in VTK_TAGFILE.
# Note: your doxyfile must be tailored to make use-of or create this tag file.
#    (using TAGFILES = vtk4-nightly.tag=http://www.vtk.org/doc/nightly/html
#        or GENERATE_TAGFILE = "@FOO_BINARY_DIR@/Utilities/Doxygen/vtk4.tag")
# Example: 
#   DOWNLOAD_VTK_TAGFILE=OFF
#   VTK_TAGFILE=vtk4-nightly.tag
#   VTK_TAGFILE_REMOTE_DIR=http://www.vtk.org/doc/nightly/html
#   VTK_TAGFILE_DEST_DIR=$DOXTEMP
